have 的使用
have 表示“有”I have a mango. 我有一个芒果。
have 表示“吃、喝”,
如:have a cake with a cherry, have some milk
Can I have a cake? 我可以吃一块蛋糕吗?疑问句形式:Do you have…?
可以跟单数,如:Do you have a banana?

can 能,会(情态动词)否定形式:cannot = can't

顾客通常用 I'd like…句型来回答。

I’d like some cakes. - (3)具体的数字用数词表示。
I’d like four cakes. 在数量超过一个的时候要注意可数名词需要用复数形式。

- (1)一个必须用 a/an/one 来表示,
Unit 7 重要知识点
How much…?这是询问价格的常用语。
如果物品是单数,可以问,如:How much is it?It's five yuan.
如果物品是复数,可以问,如:How much are they?They're twenty yuan.Well done. 干得好。常用来赞美别人某事做得好。
数词的表达:
1-12:one, two, three, four, five, six, seven, eight, nine, ten,eleven,twelve.
13-19:thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen.
整十数 20-90:twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety.
21-99 只要 先说“几十”,再说“几”,中间加连字符。如:21 twenty-one; 83 eighty- three
